Hi. Can you suggest a cooling system for B-G431B-ESC1? Easy, efficient, cheap.

I think @Valentine is a fan of recommending submersion in Fluorinert…
Maybe strapping a big heatsink across the FETs and attaching a dinky 4010 fan would be enough?
How much current are you using?

My motor use 30A and 15V

I use heat sinks on the MOSFETs plus a small fan above.
